Ok. I missed that globalized minor modes are automatically run in every

Pretty much.

I think it would be clearer to not have major modes set things that a
minor mode will then unset, but I can live with it.

Even with the current state of affairs, there's no reason to expect that a given xref backend doesn't require setting all xref variables to its own implementations.

And in the future, a minor mode will do (add-hook 'xref-backends 'foo-xref nil maybe-locally)
